How Do TENS Units Work in the Body?
Understanding what are TENS units used for becomes clearer when you see how they work.
They use small electrical signals to interact with your nervous system in two key ways:
- Blocking pain signals: The electrical pulses interfere with pain messages traveling to the brain
- Releasing endorphins: These are your body’s natural painkillers
In simple terms, the device either “distracts” your nerves or helps your body reduce pain naturally.
